To all whom it may'concern:

Be it known that we, ARTHUR W. LE Bonur and J osnrn BRADLEY Amurmos,citizens of-the United States, andresidents, res ectively, ofWoonsocket, in the county of rovidence and State of .Rhode Island, andPawtucket, in the countof Providence and State of Rhode Island, aveinvented a certain new and useful Improvement in Elevator Mechanism. ofwhich the following is a full, clear, and exact description.

This invention relates to the mechanism of a line casting machine, bymeans of which lines of matrices are raised from the casting positionupand then along a distributing rail, and are roperly presented to thedistributin IIIQCEKDISID.

The 0 ject of the invention is to provide simple and durable mechanismwhich will properly perform these functions in such wise that themachine operator will not be obliged to await the complete distributingof one line of matrices before another line can be elevated anddelivered onto and moved along the distributing rail.

The invention in its preferred form is shown in the accompanyingdrawings and is hereafter described in detail, and the construction andcombination of parts which constitute the invention are defined by theappended claims.

In the drawing, Figure 1 is a front elevation of so much of a linoty, emachine as shows the visible parts thereof which are involved in thepresent invention. Fig. 2 is a rear view of the auxiliary line carrierand some associated mechanism. Fig. 3 is a sectional side elevation inthe plane of the bent line D- D on Fig. 1. 4 is a full sized rear viewof the operating mechanism for the elevator and line carriers when therear cover of the inclosing' casing has been removed. Fig. 5 is asectional side elevation in the plane indicated by line B-B on Fig. 6.Fig. 6 isa .plan view of the operating mechanism in said casing,-.the'casing being sectioned in the plane indicated by line C-C on Fig. 4.Fig. 7 is a sectional plan in the plane indicated by line A-A on Fig.4..

Referring to the parts by numerals, 1 represents the elevator whichismovable vertically on two vertical rods, 2, 2, as guides. The elevatoris .provided with a shelf 3 adapted to support a line of matrices. Theelevator s connected with one leg of an endless chain belt 11, whichruns over an upper driving sprocket 76 and a lower idler sprocket 13.When the elevator is in its uppermost position its shelf 3 is alinedwith and in substantial contact with the left end of the distributingrail 16 which is near the top of. the machine.

The line carrier slide 4 is movable horizontally in guideways justbehind the horizontal distributing rail 16. It is connected with theupper leg of an endless sprocket, chain 12 which runs around a drivingsprocket 95 at its left end and around a suitable idler sprocket at itsright end, which idler sprocket is not shown. The line carrier slide hason its front side a yielding pressure plate 5 which extends over thedistributing rail, so as to be able to engage with a matrix linethereon.

So much of the mechanism as has been described is old in a variety ofarts. Much of the mechanism to be described is inclosed in a case 30fixed to the upper left hand corner of the machine frame, which case hasa removable rear cover 31.

The drivin clutch 35 has on its front face, within t e case 30, theratchet clutch jaws 35", and it has also a rearwardly extendedcylindrical art 35 which is rotatably mounted in a caring in the case.The driving pulley 34 is fixed to the rear end of this cylindrical part.A starting clutch shaft 41 is alined with the driving clutch, beingmounted at its front end in the casing and at the rear end in the end ofthe driving clutch.

The starting clutch 40 is a sleeve which has a feather and grooveconnection with the. starting clutch shaft 41; and it has ratchet jaws4.0 for engagement with the ratchet jaws 35 of the driving clutch, andperipheral gear teeth 40". A spring 43 acts, when permitted so to do, tomove the clutch member 40 endwise on the shaft 41 so as to cause theinterlocking engagement of the vrm.

jaws 40 and the jaws 35 This clutching movement of the clutch member 40is prevented by the engagement of a sp ral cam surface 40 on said clutchmember 40 with a pin'45 whichis carried by one arm 44* of a three armlever 44. Another arm 44 of this lever has a toe 44 which is provided togo into a'notch 47 in a disk 47 fixed to the cam shaft 56. The third arm44 of this lever lies beneath a rearwardly extended arm of the startingrod lever 49. This lever has a sleeve 49 by means of which it is pivotedto fixed bracket arms 30". It is by pushing upward on the forwardlyextended arm of the lever 49 that the mechanism is set in operation. Along downwardly extended starting rod '48 is pivotedto front arm of saidlever 49; and its lower end may be fixed to mechanism for moving it up-Ward; or the operator may take hold of it and move it upward whendesired. The resultant movement of the lever 49 will cause therearwardly extended arm thereof to rock the starting lever 44 andthereby (1) withdraw pin 45 from its engagement with the cam surface 40on the clutch member 40, whereupon the spring 43- will move said clutchmember along shaft 41, and cause it to interlock with the clutch member35; (2) will also withdraw toe 44 from the notch 47 indisk 47. Theengagement of the two clutch members 35 and 40 will cause the shaft 41.to begin to rotate, and will permit the cam shaft 56 to be rotated bythe mechanism to be described, intermediate of it and the startingclutch-shaft 41.

The elevator shaft 65 is mounted in bearings near the top of the case,and it has secured to its front end an elevator driving sprocket 76. Inthe particular construction shown, this drivingv sprocket loosely em--braces a sleeve 77 which is keyed to the shaft '65, and lies'between aflange 77 on sleeve77 and a friction disk78. A spring disk 79 whichembraces the shaftand bears against the disk 78 is put under the'properI tension by means of a nut 80, which screws onto the end of shaft 65and thrusts a- .Washer 81 against said spring disk 79. This frictionalconnection between the sprocket 76 and elevatordriving shaft 65 is asafety expedient which. will permit some rotation 2' of shaft 65independently ofthe sprocket in case anything shouldpositive'ly obstructthe -1novement of those parts which thesprocket is intended to move.Embracing this elevator shaft 65, but disconnected therefrom r aretwogears 66, 67. The latter is' always 64 which is adapted to-engage aconical recess in the adjacent face of the gear 67. On the other end ofthe sleeve 64 are cldtch jaws 64 which are adapted to engage with clutchjaws 66 on the adjacent end of the gear 66. It is obvious that when theshaft 41 is rotating, both gears 66, 67, on the elevator shaft must alsorotate, but in opposite directions, but the elevator shaft does not turnuntil by the movement of the elevator clutch sleeve 64, one or the otherof the gears 66, 67 is clutched to the. elevator shaft 65.

In order to move the elevator clutch 64, a fork lever 69 is provided,which lever is pivoted'on a vertical pivot within the case. It has atits ends a swiveled fork 68 which engages the circumferential groove 64in the elevator clutch 64. It also carries a friction roller 69 whichengages a face cam 72 on the ear 72 which is fixed to the cam shaft 56.3 spring 71 acts on this lever to hold the roller in contact with saidcam. This lever 69 has also the function of withdrawing the elevatorlatch 82 This latch is a plunger sliding through a suitable hole in thecasing wall. A. spring 83 resists its backward movement and also movesit forward beneath the shoulder on the elevator, when the elevator, ingoing up, has engaged the beveled end of said latch plunger and pushedit back. This latch carr'ies an upwardly projecting pin 85 which goesloosely into a hole in the lever 69, so that said lever, by itsmovement. rearward, may withdraw the latch. The pin; 85 is, as a matterof construction, fixed to a block 85 which slides looselyon the stem 83,being held upon said stem by the head 85.

v The cam shaft 56, before referred to, carriesthree cams,,viz the facecam 7 2 which and it also carries the notcheddis'k47 be-' "is on' theside of a large gear ,72 which is fore referred to. .The gear 72 meshes.with I,

an intermediate pinion 58, which is'rigidly connected with anintermediate. gear 57 which is rotatably mounted on the fixed stub shaft59. I The gear 57 isin mesh with a pinion 41. carried by the clutchshaft 41.

The cam 86 is for the immediate purpose of moving the segment frame87-which isloosely hung on theelevator [shaft 65. This frame carriesafriction roller 87 adapted to be engaged by the cam 86. A spring 88acts toswmg thesegment'in the opposite direction to that in which thecam moves it.

The gear teeth on this segment frame engages ag'pinion 92 which is fixedto gear 93,

said gear and pinion being rotatably mounted .on a shaft 99. The gear 93is in mesh with a pinion 94 on the line carrier driving shaft 96 to,which the line carrier driving sprocket 95 is fixed. The line carriersprocket chain 12 runs over this sprocket and over another sprocketwhich is not shown, to the right thereof, and, as before stated, theline carrier slide is fixed to the parting its movement to the slide.

upper leg of this sprocket chain. Theother cam 108 is for operating theauxiliary line carrier. Thiscam engages with a friction roller on theauxiliary :line cam :lever 109; and a spring 110 acting-on the lever,moves it in the.oppositeudirection. A link 111 connects this lever 109"with another lever 112,, which is connected by a link 113 with theauxiliary line carrier, and particularly with a slide 20 which forms apart thereof.

Whenever the elevator rises, carrying with it a line of matrices, thisline is swept off the elevator onto the distributing rail by. the linecarrier, and along said rail until the foremost matrix in a line comesagainst a stop 115, which is a part of the distributing mechanism. Thisdistributing mechanism, although no part of the present invention,includes means by which the matrix at the right end of the line issegregated from the line and sent along to its appropriate magazine. Theline carrier being spring-actuated will .move the line to the rightwhenever the right end matrix is removed so that the next matrix willcome against said stop and be in a position to be ,segregated. But itfrequently happens that before this line has been entirely distributed,another assembled line of matrices will have been put onto the elevatorin readiness to be taken up to the distributing rail. In order that thedistribution of the matrix line may be continued, while the line carriergoes to the left in order to bein the proper position when the elevatorcomes up, the auxiliary line carrier referred to is provided. Thisincludes a slide 21, which is movable in a suitable horizontal guidewaybelow the distributing rail. The sliding bar 20, before mentioned asconnected by link 113, wit-h lever 112, is supported on the slide insuch wise that it is permitted to move horizon-' tally a limiteddistance only, before im- It has a horizontal slot 20 through whichprojects a stud 21 fixed to the slide, and it has also a stud 20 whichprojects through a horizontal slot 21 in the slide. The right end of thelink 113 is pivotally connected with the rear side of the sliding bar20.

Pivoted to the front side of the slide are two parallel links 22, 23, tothe right ends of which are pivotally connected the auxiliary linecarrier push bar 24. This projects upward and pasms into and may passthrough a vertical slot 16 in the distributing rail 16. The upper of thetwo parallel links has at its left end a downwardly extended finger 22adapted to be engaged by the head of a stud 20 which as stated is fixedto the sliding bar 20. A spring 25 acting upon the upper link 22 tendsto swing it so as to carry the auxiliary line carrier push bar 24 upthrough the slot in the distributing rail and behind a line of matricesthereon. But

when the sliding bar is moved to the left, the head of stud 20 willstrike the :finger 22 of the :upper link 22 and so rock it as to drawthe auxiliary line carrier push her 24 down below the top of thedistributingrail. Whemthe sliding bar is moved to the right, it carriesthe head of stud 20 out of engagement with said 'finger, whereupon thespring 25 rocking the link 22 will carry the push bar 24 up so that itsupper end is above the top of the distributing rail, .so that it mayengage with a matrix resting upon said rail. The power to rock lever 109in the direction which carries the auxiliary line carrier to the leftcomes from the cam 108 which, as stated, engages said lever 109 andswings it. When this cam has, through the described mechanism, movedsaid auxiliary line carrier mechanism to the left, the cam releases itsengagement with said lever, whereupon a spring 115 moves the lever inthe contrary direction. The spring 27 is fixed to the auxiliary linecarrier slide, and by pressing against the adjacent fixed frame member,acts as a brake or drag which makes it certain that said slide shall notmove until after the sliding bar 20 has moved relatively to said slide,as before ex plained.

The described mechanism operates as fol- 9 .87, and therefore thisframe, under the influence of the spring 88 is, through the train ofmechanism described, acting on the line carrier, to move it to theright, and thereby keep the matrix line moving along the distributingrail toward the distributing mechanism. The cam 108 is. however, actingupon lever 109, and holding it and the auxiliary line carrier mechanismat the extreme left ends of their paths.

The mechanism is at rest because the pin 45 is engaged by the high partof the spiral cam surface 40 on the starting clutch. whereby saidstarting clutch is held out of engagement with the driving clutch.\Vhcn, now, the operator gives the upward movement of the starting rod48 and, consequently, rocks the lever 49, this latter lever will rockthe three armed lever 44, thereby releasing the cam shaft fromrestraint, and (2) withdrawing pin 45 from engagement with the spiralcam 40", which permits the starting clutch 40 to be moved by its spring43 into clutching engagement with the driving clutch 35. The shaft 41 isthereby caused to rotate, and it, through the described train ofmechanism, rotates the cam shaft, which thereafter continues to turnuntil it has made one complete revolution. At the end of that time thetoe 44 will drop into notch 47; and, as the result of rocking of lever44, the pin 45 will move into the path of the spiral cam 40, which cam,by

a. aoeaeee its engagement with said pin, causes the starting clutch 40to move away from and out of engagement with the driving clutch 35. Thisdisconnects the mechanism from the source of power, so that it will bedisposed to stop; and the engagement of the rear end of notch 47 withthe toe 44 causes the cam shaft to stop in exactly the right position.

While the cam shaft is in rotation it produces the following results:lit, first, turns cam 108 so as to release the auxiliary line carrierfrom restraint. Thereupon the auxiliary line carrier spring 112, actingthrough the described train of mechanism, causes such a movement'of theauxiliary line carrier to the right, as will cause its push bar 24 tomove into contact with the left matrix on the distributing rail,'andwill thereafter continue to move the matrix line in the distributingdirection until the auxiliary line carrier is again drawn to the left bysaid cam 108. It will be understood that the power to move the auxiliaryline carrier mechanism to the right is applied to the sliding bar 20,which first moves a short distance independently of the slide. -By somoving, it releases the upper link 22 from restraint, and the spring 25vcauses said link to so swing as to carry the auxiliary line carrier pushbar 24 up through the slot in the distributing rail into operativeposition. This being accomplished, a further movement of the sliding barto the right will cause a corresponding movement of the slide, and allthe parts supported thereon. As the camshaft rotates, the cam 72 willmove the elevator clutch lever so as to carry the elevator clutchforward into engagement with the jaws of the gear 66, whereupon theelevator shaft will begin to rotate clockwise (when viewed from thefront) and theelevator will begin to rise. At about the same time thecam 86 will begin to act' on the s ag ment frame 87, and to swing itinsuch'wise that the line carrier mechanism is drawn to the left until itspressure plat/e5 is at the left of the path in which the elevatormovesupward. Just before the elevator reaches the top of its path ashoulder 1f thereon will engage the plunger latch- 82 and push it back,and then said latch will fly forward under said shoulder and temporarilyact to hold the elevator up andin exactly the proper position relativeto the distributing rail 16, when the elevator is settled backso as torest upon said plunger latch. When the elevator has passed the plungerlatch in its upward movement the cam 72 will have come to such positionthat the clutch leverwill be moved to carry the elevator clutch intointermediate position, whereupon the elevator shaft stops its rotation.This condition of the mechanism is maintained while cam 86 backs offfrom the segment 87 and allows the spring 88 to so swing it as to movethe line carrier to the right. By this movement the" line carrier willsweep the matrix line from the elevator onto the distributing rail andalong said rail to the distributing mechanism. Thereafter the cam 72 byits advance allows the elevator clutch lever to be moved by its springso as to move the elevator clutch rearward into clutching engagementwith the gear 67. This move-v mentof theclutch operating lever withdrawsthe latching plunger; whereupon the elevator clutch shaft begins torotate counter clockwise and moves the elevator, down. As the elevatoris reaching its down position the cam 72* will move the clutch operatinglever *69 so as to carry the elevator clutch into its neutral positionwhich'causes the elevator shaft to cease rotation. lathe meantime cam108 has moved'th'e auxiliarv line carrier mechanism to the left; that isto its initial'position. When these results have been accomplished thecam shaft will be near the end of its single revolution; the toe 44 willdrop into notch 47, the pin 45 will move into position to be engaged bythe spiral cam 40, and this engagement will cause the endwise movementof the starting clutch and disconnect it from the driving clutch. Themechanism having performed its functions will now come to rest.

A bracket 43 is fixed to the auxiliary line carrier slide 21 and extendsupward and has pivoted to its upper end on a horizontal rearwardlyextended pivot the arm 42, which arm is under the influence of, a spring44 tending to rock it to carry its right end downward as far as it,cango'until a rearwardly'extended tail piece 47 'engagesa stop pin 46 fixedto the bracket 43. This arm 42 will, when the auxiliary line carrier isin operation, engage the upper part: of the leftend matrix in theline,and will keep it from falling over. In fact, this arm 42 cooperates withthe auxiliary line carrier 24 in pushing thematrix-line along the distributing rail. When amatrix line is being moved by the line-carrierpastthe auxiliary line carrier mechanism, the upper edges of the matrixwill, by engaging the arm 42, lift it so that they may pass beneath it.
